23 Claims.

This invention relates to a sewing machine of the general type disclosedand claimed in my copending application Serial No. 744,642, filedSeptember 19, 1934.

5 A prime object of the invention is to provide a novel and improvedsewing machine whereby the direction of feed of the Work can be changedat will approximately instantaneously at sharp angles without manualmanipulation or turning of the work and without interruption of theoperation of the machine to form in one continuous operation a pluralityof lines of stitches extending in different directions and meeting atangles.

The invention is especially suitable for sewing two seams of a garmentat angles to each other, or sewing a label to a garment with acontinuous line of stitches extending around the marginal portions ofthe label, although many other uses of the invention will occur to thoseskilled in the art.

In accordance with preferred embodiment of the invention, 1 may utilizea sewing machine which includes a drive'shaft, a stitch formingmechanism, and a work feed dog which is operatively connected to thedrive shaft by connections certain of which move the dog horizontallyback and forth while he other actuates the dog vertically up and down,the dog being raised 30 and moved hor zontally in one direction inengagement with the work to move the latter and then being lowered awayfrom the work and moved horizontally in the other direction to itsinitial position, so that the work is moved horizontally relatively tothe stitch forming mechanism. In known sewing machines of this generalcharacter the feed dog is movable horizontally in only two directlyopposite directions so as to move the work in one direction, but in my40 aforesaid copending application and in my application Serial No.736,806, I have shown means for also periodically varying the operationof the feed dog to reverse the work feeding movement thereof. My presentinvention contemplates a machine of this character wherein the operationof the feed dog can be varied at will to reverse the feed of the work,or to cause the work to be fed successively in directions at rightangles to each other, or to cause the work to be fed diagonally. v

More particularly the invention contemplates rovel and improved meansfor horizontally actuating the feed dog back and forth in oppositedirections, other means for operating the dog back and forth indirections at right angles to the first-mentioned directions, and meansfor causing a composite or simultaneous movement of the first twomentioned means for actuating the feed dog back and forth in directionsdiagonal to the first two named directions, whereby, for example agarter may be stitched to a corset by continuous lines of stitchesarranged in the form of a rectangle and other lines of stitches disposeddiagonally of the rectangle, in one continuous operation.

A further object is to provide a multiple direction sewing machine whichshall embody two needles in the stitch forming mechanism and novel andimproved work feeding mechanism whereby two parallel lines of stitchesmay be formed in one direction and a line of double stitches can beformed at the ends of said parallel lines and disposed at right anglesthereto without turning the work and without breaking of or loosethreads or loss of stitches.

The invention further has in view the cooperation with all of said meansfor horizontally moving the dog, of a common means for operating the dogvertically or up and down to engage and disengage the work.

Other objects of the invention are to provide a machine of the characterdescribed which shall be relatively simple, reliable, durable andinexpensive in construction and operation, and to obtain otheradvantages and results as will be brought out by the followingdescription.

Specifically describing the illustrated form of the machine embodying myinvention, the reference character A designates the bed plate of themachine which has the usual standard B ther on formed with a goose neckC at one end of which is mounted the needle bar D. The needle bar isdriven in the usual way from the drive shaft E of the machine which isjournaled in the standard B and goose neck C. With the need bar and itsneedle. cooperates a bobbin mech anism F of the usual type, the needlebar and its operating devices and the bobbin and its .journaled in thebed of the machine.

operating parts constituting a stitch forming mechanism.

The machine also includes work feeding mechanism for moving work throughthe stitch forming mechanism, that is, between the needle and the bobbinmechanism, and as shown, this work feed mechanism includes a feed. dog Iwhich is movable vertically and horizontally relative to the usualthroat plate 2 in the bed of the ma-' chine, the dog being raisedthrough the throat plate and moved horizontally in one direction inengagement with the work to move the latter and then being lowered awayfrom the work and moved horizontally in the other direction to) itsinitial position. Cooperating with the feed dog in the usual manner is aknown type of presser foot G. The dog is operated from the drive shaft Eof the machine and as shown is mounted on a link 3 one end of which isbifurcated at 4 and has a pin and slot connection 5 with a crank 6 on acounter shaft 1 journaled in the bed plate of the machine. The other endof the link 3 is pivotally connected at 8 to a crank 9 on anothercountershaft ID The countershaft I is rotated alternately in' oppositedirections by a crank arm H connected to the shaft and having abifurcated end 12 in which rotates a cam l3 mounted on a secondary driveshaft I4 which is journaled in the bed of the machine and is driven bythe usual crank and pitman connection l5 from the drive shaft E. Withthis construction, the counter shaft 1 is rotated alternately inopposite directions so as to vertically raise and lower the said dog Ithrough the throat plate 2 into and out of engagement with the work.

For actuating the feed dog horizontally back and forth to feed the workforwardly or backwardly, the counter shaft is rotated alternately inopposite directions. As shown. the

countershaft I0 has a pin l1 projecting laterally through a slot IS inthe bed plate of the machine, the end of the pin being arranged to entera slot in an actuating slide 2| so that the pin may have a hinged orpivotal connection with the slide and reciprocation of the slide willcause rotation of the shaft 10 alternately in opposite directions. Asshown, the slide 2| is longitudinally reciprocable in a channel shapedguide 22 which is pivotally mounted at one end 23 on the bed of themachine.

One end of the slide 2| has a pin and slot connection 24 with one end ofa lever 25 (see Figure 31) which is pivotally mounted at 26 on ahorizontal axis on a bracket 2'! secured upon the top of the bed A ofthe machine. Carried by the lever 25 is a follower roller 28 which isarranged in the cam groove 29 of a box cam 30 (see Figure 2). This cam30 is mounted on an auxiliary shaft 3! that is journaled with its axisvertical in bearings 32 and 33 and which has a worm gear 34 which mesheswith a worm 35 on the drive shaft E. The cam groove 29 has cam surfaces36 which will be hereinafter described in detail, so that upon rotationof the cam through the gearing 34 and 35 the lever 25 will be oseillatedabout its pivot to reciprocate the actuating slide 2| and rotate theco-untershaft if! when the pin I! is in the notch 20 so as to actuatethe feed dog l horizontally and vary the operation thereof.

For engaging'alid disengaging the actuating slide 2! with the pin ii,the guide channel 22 is oscillated about its pivot 23, and for thispurpose I have shown a knee operated lever 31 pivotally mountedintermediate its ends 38 on a bracket 39 secured to the front of the bedof the machine, one end of thelever 37 having a pin and slot connection40 with a down-turned end of the guide channel and the other end of saidlever having a knee rest adjustably connected thereto to be engaged bythe knee of the operator. By pressing the knee rest M to the right inFigure lof the drawings, the guide channel may be swung to the left tocause engagement of the pin I! with the notch 20, and upon release ofthe knee rest, a tension spring 52 will swing the guide channel in theother direction to disengage the pin I! from the notch 20.

For controlling the reciprocation of the actuat ing slide 2| the camsurfaces 36 of the cam 30 may be of any suitable configuration, forexample, as shown in my copending applications Serial Nos. 736,806 and744,642; but for simplicity in explanation, I have shown the camsurfaces as formed and arranged to produce a continuous line of stitchesof equal length. The cam surfaces for each stitch are identical, so thatI shall describe only one.

Referring to Figure 2 of the drawings, each cam surface includes a dwell43 which when engaged by the follower roller 23 actuates the slide 2| sothat the feed dog is at the beginning of its forward feed movement inengageinent with the work as shown in Figure 6. In this position of thefeed dog the shaft 7 has raised the feed dog into engagement with thework and holds it there during horizontal movement of the feed dog tothe right in Figure 6. This horizontal movement is caused by an inclinedsurface 44 on the cam which causes the slide to be operated and move thefeed dog to the end of its horizontal feeding movement; 1. e. at theextreme right of the opening 2 in the throatplate in Figure 6. When thefeed dog reaches this position, the cam 30 has rotated to bring thefollower roller 28 into engagement with another dwell 45 whichinterrupts horizontal move-- ment of the feed dog while the shaft '1lowers the feed dogaway from the work. Thereupon the roller 28 isengaged by another inclined surface 46 which moves the feed dogbackwardly or to the left in Figure 6 to the beginning of its forwardwork feeding movement. The dwell 43 then engages the follower roller tointerrupt horizontal movement of the feed dog while the shaft 1 raisesthe feed dog into engagement with the work at the beginning of itsforward feeding horizontal movement, whereupon the continued rotation ofthe cam 30 brings the next inclined surface M into contact with theroller to cause another horizontal feeding movement of the feed dog.This cycle is then repeated throughout the rotation of the cam, onestitch being formed during each horizontal feeding movement of the feeddog, as usual.

In accordance with the invention, the direction of feeding movement ofthe feed dog may be reversed at will, and as shown in Figures 1 to 6inclusive, this reversing movement is effected by manipulation of theworm 35 on the shaft E. The worm 35 has a key or feather and splineconnection with the shaft E so as to move longitudinally of the shaft,and has a circumferentiallygrooved collar 4'! in which rides a followerroller 48 on a pin l9 connected to a reversing slide 50 reciprocable ina guide bracket 51 on the top of the goose-neck of the machine.

next

The reversing slide is reciprocated by an operating bar 52 slidablymounted in the bracket 5| in a direction at right angles to the plane ofreciprocation of the reversing slide 50. The operating bar has a camslot 53 which engages a pin 54 on the reversing slide so that uponmovement of the operating slide in opposite directions, the reversingslide is reciprocated in opposite directions respectively. Any suitablemanual or automatic means may be utilized for moving the operatingslide, but I have shown a foot lever 55 connected by a chain or cord 56to one end of the operating slide for moving the slide in one direction,a tension spring 51 being provided for moving the slide in the otherdirection upon release of the foot lever. If desired, a handle 58 may beprovided on the operating slide for actuating it in both directions.

The ratio of the movements of the various parts is such that when thereversing slide 55 is moved in either direction, the worm 35 is slid onthe shaft E a distance sufiicient to rotate the cam 30 in one directionor the other relative to the follower roller 28 a distance adequate tocause a reversal of movement of the feed dog. This manipulation oradjusment of the cam is schematically illustrated in Figures 9 to 11inclusive. Assuming that in Figures 9 and 10 the cam is rotated in thedirection of the arrows and the follower roller 28 has moved from theposition of Figure 9 to the position of Figure 10 so as to havecompleted a forward feeding'movement of the feed dog, operation of thereversing slide 50 to the right in Figures 2, '7 and 8 will cause thecam to be moved in the opposite direction as indicated by the arrow inFigure 11 so that the roller and cam will be returned to the samerelation as shown in Figure 9. This will result in a movement of theactuating slide and feed dog backwardly or in a direction opposite tothe movement effected during operation of the parts from the positionshown in Figure 9 to the position shown in Figure 10. Therefore, uponresumption of normal rotation of the cam 30 in the direction of thearrows shown in Figure 9, the feed dog will feed the work backwardly. Inother words, the dog will engage the work while it is moving from rightto left of Figure 6 instead of while it is moving from left to right.This reversal of movement of the feed dog may be effected at any timeand in any position of the feed dog. When this reversing movement of thefeed dog takes place while the shaft 1 is moving the feed dog downwardlyaway from the work, no stitches will be formed during the reversal, butwhen the reversal is made while the feed dog is in engage,- ment withthe work, a stitch will be produced on top of the next preceding stitch.Obviously movement of the operating slide 52 in opposite directions willcause reversals of movement of the feed dog in opposite directionsrespectively. Preferably, the feed dog has a knurled surface to properlygrip the work on movement in both directions.

In Figures 43 to 56 inclusive are illustrated the operations of the feeddog in forward feeding and reverse feeding of the work. Figure 43 showsa line of stitches formed upon forward feeding of the work and Figure 44shows the position of the feed dog i at the end of the .forward feedingmovement where the dog is in its upper position in engagement with thework W shown in dot and dash lines. Figure 45 shows the dog lowered awayfrom the work as the result of movement of the shaft 1 while Figure 46shows the movement of the dog to the beginning of its forward feedingstroke but out of engagement with the work. Figure 47 shows the dograised into engagement with the work preparatory to beginning the nextforward feed of the work and Figure 48 shows the dog at the end of theforward feeding. When the operating slide 52 is actuated to reverse thedirection of the work with the feed dog in the position shown in Figure48, the dog is moved backwardly as shown in Figure 49. Thereupon the dogis lowered away from the work as shown in Figure 51 and then forwardlyout of engagement with the work as shown in Figure 52 and then upwardlyinto engagement with the work as shown in Figure 53 and then backwardlyin engagement with the work as shown in Figure 54 so as to move the workbackwardly. This results in a reverse stitch designated by the referencecharacter a in Figure 50. The dog is then moved downwardly away from thework after which this cycle of operations may be repeated to form adouble row of stitches designated b in Figure 58.

The invention also contemplates a lateral or sidewise feeding of thework, and for accomplishing this result, I have shown the feed doglaterally horizontally reciprocable. Specifically the crank 9 has akeyed or feather and spline connection with the shaft l so as to slidelongitudinally of the shaft and is influenced in one direction by acompression spring 59 interposed between the crank and a collar 60 onthe shaft The crank has a lateral arm 6| to one end of which isconnected a pull rod 62 the other end of which is connected to one arm63 of a bell crank lever 64 which is journaled on a stub shaft 65 on thebed of the machine. The other arm 66 of the bell crank has a head 61 toengage a notch 61' in the actuating slide 2|. With this construction,when the actuating slide is connected to the head 61, reciprocation ofthe slide by the lever 23 will cause oscillation of the bell crank lever64 and consequent horizontal lateral movement of the crank 9 and feeddog I (see Figure 42). This horizontal lateral movement of the feed doghas a timed relation to the vertical motion of the feed dog effected bythe shaft 1, corresponding to the timed relation of the horizontallongitudinal movement of the feed dog and said shaft 1. The bifurcatedend I2 of the link 3 slides longitudinally of the pin on the crank 6 tocompensate for the sliding of the crank 9 longitudinally of the shaft[0.

Another feature of the invention is means for causing feed of the workin directions which are composites of the longitudinal and lateralfeeds, that is, a feed of the work diagonally. This diagonal feed may beeffected by causing oscillation of the crank 9 and longitudinal movementthereof on the shaft ID at the same time; in other words, by causing theactuating slide 2| to engage both the pin I! and the head 61 of the bellcrank lever 64. In order to so simultaneously connect the pin l1 and thehead 61' to the actuating slide I have shown the arm 66 of the bellcrank lever as extensible. In Figures 12 to 16 inclusive, this arm 66includes a main portion 69 on which is longitudinally slidable anextension portion at the end of which is mounted the head 61. A latch His pivotally mounted on the extension ill to cooperate with openings 12in the main section 69 for holding the extension 10 in adjustedpositions. When it is desired to connect the head 61 to the actuatingslide 2| simultaneously with the connection of the. slide to the pin ii,the extension i9 is slid outwardly into the position shown in Figures 15and 16, while when it is desirable to connect the actuating slide 2| toeither the pin I! or the head 61, separately, the extension 10 is slidinwardly into the position shown in Figures 12 and 14. When theextension is in this position, the actuating slide 21 may also belocated in neutral position,

that is, unconnected with either the pin it or the head El as shown inFigure .12. As shown, the head 61 and pin ll are preferably located atopposite sides of the slide 21 to facilitate these operations.

In operation of the mechanism, when the actuating slide 21 is in neutralposition as shown in Figure 12 the slide may be reciprocated by thelever 25 without any horizontal motion of the feed dog. To causehorizontal longitudinal motion of the feed dog, the actuating slide 2!is swung to the left as shown in Figure 13 to engage the pin 17, whilewhen it is desired to cause simplylateral motion of the feed dog, theactuating slide is swung to the right as shown in Figure 14 to engagethe head 61, while when diagonal motion of the feed dog is desired, theactuating slide is swung into engagement with the pin I! after which thebell crank arm 66 is extended to engage the head 6? with the actuatingslide, as shown in Figure 15.

Figure 17 is a schematic plan view of the feed dog operating mechanismwith the parts in neutral position, while Figure 18 shows the parts inthe position assumed for beginning longitudinal horizontal movement ofthe feed dog. Figures 19 and 20 show the actuation of the slide 2! andthe feed dog E successively in opposite directions.

Figures 21- to 23 inclusive show the corresponding steps in thehorizontal lateral reciprocation of the feed dog. Figure 24 shows theposition of the parts preparatory to beginning diagonal horizontalactuation of the feed dog, while Figure 25 shows the completion of theadjustment of the parts for such diagonal lateral motion.

Figures 26 and 27 show the operation of the parts successively inopposite directions during diagonal actuation of the feed dog and Figure28 shows the disconnection of the head 81 from the actuating slide.

With the feed dog moving horizontally either longitudinally, laterallyor diagonally the dog may be caused to move in either of the other twodirections at the will of the operator. Furthermore, the feed dog may atwill be caused to feed in either of opposite directions longitudinally,laterally or diagonally. In Figure 57 the feed dog is shown as havingbeen changed from backward longitudinal feeding to lateral feeding, thedog being disengaged from the work at the begin ning of lateral feedingof the work in the direction of the arrow. Figure 59 shows the dograised into engagement with the work at the beginning of the feedingmovement while Figure 61 shows a dog at the end of the feeding movement.Figure 62 shows the dog being lowered away from the work and Figure 63shows it returned to the initial position shown in Figure 57. With thedog moving in this manner, a lateral line of stitches 0 may be formed.In Figure at the direction of lateral movement of the dog is shown aschanged so as to reverse the direction of feed of the work as indicatedby the arrow,

the dog being disengaged from the work. Figures 65 and 66 show the dogatthe beginning and ending of its feeding movement respectively, whileFigure 6'7 shows the dog lowered away from the work at the end-of thefeeding movement. This operation will result in a double line of lateralstitches 0 shown in Figure 64. Figure 68 illustrates a change in themovement of the dog from lateral feeding to diagonal feeding, the dogbeing shown out of engagement with the work. In Figure '70, the dog isshown as moved out of engagement with the work to the beginning of itsdiagonal feeding motion while Figure 71 shows the dog raised intoengagement with forward longitudinal feeding, Figures '75- to '77showing the cycle of operations of forward feeding from a line ofstitches e. In Figure 78-the position of the dog is shown as againchanged to feed diagonally in the direction opposite to that illustratedin Figures 70 to '72 inclusive so as to form a diagonal line of stitchesf; Figures 80 to 82 inclusive show the steps in the cycle of movement ofthe dog. In Figure 33 the direction of movement of the dog is againillustrated as longitudinally forward to form a stitch g, Figure 84illustrates the end of the forward feed movement. In Figure 85 the dogis shown as stationary as when the-machine is stopped.

All of the stitching hereinbefore described, is formed with a singleneedle, out the invention is of course susceptible of use in a two.needle machine. Here two needles are used, parallel rows of stitchinghand i may be formed as shown in Figures 8'7 and 39 or arow ofdoublestitches k may be formed in one operation as shown in Figure 88. Byfeeding the work longitudinally parallel rows Z of single stitches may.be formed, and then by feeding the work laterally a row of doublestitches m may be formed at right angles to the rows Z. scribed issimply illustrative of the many different forms of stitching which maybe accomplished with my machine, and it will be understood by thoseskilled in the art that the machine may be used for making various formsof stitches without departing from the spirit or scope of the invention.a

It will be understood from the foregoing that the drive worm 35 inconnection with the re? versing slide 50 may be utilized for reversingthe direction of movement of the feed dog when the dog is moved eitherlongitudinally, laterally, or diagonally.

Instead of manipulating the worm 35 to reverse the direction of feedingmovement of the feed dog, I may move the follower roller 28 rela- Thestitching detively to the cam. A structure for accomplishing 19journaled in the bed of the machine and having a crank arm 86 which isconnected by aslide.

link 8! to the bracket. Obviously, by sliding the bracket laterally, theposition of the follower roller 28 relative to the cam may be varied asshown in Figures 39 to 41 inclusive. This adjustment corresponding tothat illustrated in Fig ures 9 to 11 inclusive for efiecting reversal ofthe direction of movement oi the feed dog.

To compensate for the sliding movement of the bracket, the pin and slideconnection between the lever 25 and the actuating slot 2! must permitlateral movement of the lever relative to the slide, and as shown inFigure 34 the slot in the lever may be elongated as indicated at 83 toslide laterally of the pin or stud 84 on the actuating The machine shownin Figures 29 to 36 otherwise operates in the same manner as the machineshown in Figures 1 to-6 inclusive.

Figures 37 and 38 are schematic comparative views of the two ways ofcausing relative adjustment of the cam and follower roller, Figure 3'7showing the adjustment eiiected by movement of the worm 35 as shown inFigures 1 to 6 inclusive, while Figure 38 shows the adjustment efiectedby moving the bracket as shown in Figures 29 to 36 inclusive.

Instead of moving the followerroller 28 relative to cam 30 for reversingthe feed, I may provide any suitable known type of reversing mechanismfor simply reversing the direction of rotation of the cam.

While I have shown the cam 39 in the form of a box cam, it will beunderstood that a plain cam 82 may be utilized as shown in Figure 32.However, where a plain cam is used, a spring 10A must be provided forholding the follower roller in engagement with the cam (see Figure 3 ofthe drawings).

It will be understood that the invention is also susceptible of use in asewing machine having a vibratory or oscillating needle bar.

While I have shown and described my invention as embodied in certaindetails of construction and as utilized for certain purposes, it shouldbe understood that this is primarily for illustration of the principlesof the invention, and that the machine may be embodied in other detailsof structure and used for other purposes without departing from thespirit or scope of the invention.
